USB2 hub helps with USB1.1 keyboard and mouse

My 8GB late 2009 iMac complained of no mouse or keyboard when running the patched Sonoma installer.
I was warned by OCLP.
I tried a handy pair of devices - detected as 1.1.
I tried a DELL dongle - also 1.1.
Plugged the 1.1 devices into a 2.0 hub and installation succeed.

With 14.7.2 installed, upgraded to 14.7.3 - seemless but slow to install.
OpenCore detect the change and applied the patches - hub still required until patched.
Next for 15.3 - done! Aw damn! Now for 15.3.1 - OK.

Hub and KB/M stored for another day.

PS dual boot to 10.x, and the Sequoia partition cannot be seen but option-boot works.
